Application filed february 28,1911. Serial No. 611,450.

To all 'whom it may concern: Y y

Be it known that I, GEORGE IV. BEADLE, a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Removable End Closures for Cartons; and I do hereby declarethe following to be a full, clear, and exact description of the invention, such as m will enable others skilled in the art to which it appertains to make and use the same. My invention relates to improved closures vtor vessels, and it consists in the .constructions, combinations and arrangements herein described and claimed.

` An object of my invention is to provide an improved closure of fibrous material adapted to firmly support the walls of a vessel and to be automatically clamped in locking engagement with the exterior of Such firmly supported walls.

A further object of my invention is to provide an inexpensive closure of fibrous material adapted to be positively vclamped in locked positionl and to be readily removed and replaced in position.

A further object of my invention is to provide an improved closure which will eiilciently protect the pouring lip of a vessel and lie flush with Ithe vessel walls, thereby constituting a sanitary construction which provides smooth and unbroken adheringl surface for labels.

In the accompanying drawings, formlng a part of this application, 'and in which similar reference symbols indicate corresponding'parts in t-he several views z-Figure 1 is an elevation, partly in section, illustrating one embodiment of my invention; 40 Fig. 2 is a view similar to Fig. 1, illustrating a slightly modified construction; and Fig.A 3 is an enlarged detail section, showing'meansy for applying the closure illus- `,trated in Fig. 2. K i Referring especially to Figs. 2 and 3 of fthe drawings, 1 indicates the cylindrical body' of a cart-on or vessel, of suitable .material, which is crimpedv circumferentially adjacent to. its-pouring lip 4 to provide an exterior annular groove 3 and -av corresponding interior shoulder 2. A closure of suitable fibrous, flexible' material, such as paper, is shown comprising a disk 5 crimped, or folded, to provide a still", reinforced, an-

nular sleeve 6 of double thickness 'of thema- -terial, adapted to closely fit the interior ofv the carton walls for firmly sciipporting and bracing the latter against distortion, and to seat 'against the interior annular shoulder 2 for supporting all axial thrusts on the closure and protecting the edge of the pouring lip 4: from injury thereby. The closure is provided with an integral, annular, elastic, stretchable a ron 7 spaced concentrically about said still sleeve 6 for clampingly engagmg the exterior of such firmly-supported carton walls, and provided with an interior annular bead 8 adapted to spring in locking engagement with the annular .groove 3.

Fig. 1 illustrates a slight modification, 1n which the annular bead 8 is 'formed at a slight distance from the end of the apron 7, thereby providing a exible sealing lip below said bead.

From the' above description, it will be clearthat my invention' provides an improved closure of fibrous material adapted to efliciently protect the pouring lip against contamination, and to be readily removed and placed in position; said closure extending Substantially liush with the exterior surface of the carton to provide a smooth and unbroken adhering surface for labels.

1. The combination of a vessel having its walls crimped circumferentially to provide an interior shoulder spaced from its pouring lip, and a closure provided with a re- 1n o-rced sleeve of double thickness of material adapted to closely fit the interiorof the vessel Walls for firmly supporting the latter and to seat against said interior shoulder, and with an elastic; stretchable apron adapted to clampingly engage the exterior of said vessel about said supporting sleeve.

2. The combination of a-vessel having its walls crimped circumferentially to provide an exterior groove and an interior shoulder spaced from its pouring lip, and a closure provided with a reinforced sleeve ot double -thickness of material adapted to closely lit the interior of the vessel walls for firmly supporting the latter and to seat against said interior shoulder, and with an elastic, st-retchable apron adapted to clampingly engage the exterior of said vessel about said .supporting sleeve and provided with an annular bead for lockingly engaging such exterior groove. f

3. The combination of carton having its walls crimped circumferentially to rovide an exterior groove and an interior s oulder spaced from its pouring lip, and a flexible closure of fibrous material formed with a reinforced sleeve of double thickness of said material adapted to closely fit the interior of the carton walls for firmly supporting the latter and to seat against said lnterior shoulder, and with an integral, elastic, stretchable apron adapted to clampingly en- In testimony whereof, I aix my signa-y ture, in presence of two Witnesses.
